CLEVIS ADJUSTMENT FOR FLOWS.

Specification of Letters'Patent.

Patented Sept. 28, 1920.

Application filed. May 10, 1920. Serial No. 380,353.

T 0 all whom it may concern Be it known that I, ALFRED A. BRYANT, a citizen of the United States, residing at Easley, in the county of Pickens and State of South Carolina, have invented certain new and useful Improvements in Clovis Adjustments for Flows; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to a elevis adjustment for plows, and has for its object to provide a device of this character which will be simple in construction, comparatively inexpensive to manufacture and more convenient and eliicient in action, than those heretofore proposed.

With these and other objects in view, the invention consists in the novel details of construction and combinations of parts morefully hereinafter disclosed and particularly pointed out in the claims.

Zieferring to the accompanying drawings forming a part of this specification, in which like numerals designate like parts in all the views:

Figure 1 is a side elevational view of a plow with my invention applied thereto; and

Fig. 2 is a sectional view on the line 2-'2 looking in the direction of the arrows.

1 indicates any suitable elevis pivoted as at 3 to the end 2 of the plowbeam, and provided with the extension 4, adapted to swing around the bolt 3 between the stops 5 and 6 with which said beam end 2 is provided. The plow beam 8, is provided with the slot or opening 9 in which fits the slidable block 10, secured by the bolt 11 to pitman or other connection 12, pivoted as at 13 to the hand operated lever or handle 14 pivoted to the plow or beam as at 15. 16 represents the plow point, 17 the under flat surface thereof or plane of the furrow being plowed, while 18 is the mold board or wing of the turn plow shown.

It is well known that in plows of the usual construction, it is much harder work for the plowman to plow hillsides than it is to plow level fields. The reason for this is also well known, and is found in the fact that when the soil is being shed by the wing 18 up-hill, the point 16 of the plow and the lower flat surface 17 runs at a lesser depth than when the soil is being shed by the wing 18 down hill. Therefore, it is evident if this inequality in the depths of the up-hill and downhill furrows can be corrected, the work of the plowman will be lessened. To do this, the angle between the line of pull on the bolt 3 and the plane of the bottom 17 may be varied as follows, in order to produce up hill and down-hill furrows of the same depth: When the furrow to be plowed is a down-hill furrow, the above mentioned angle is lessened by drawing back the lever 14: and pulling back the block 10, thus permitting the extension 4 to rise and the elevis 1 to fall. t should be observed that the weight of the double tree and attachments, not shown, serves to weight down the elevis 1 and therefore to normally lift the extension 4. toward the pin 5, and when power is be ing exerted on said elevis 1 it is not very easy to adjust the block 10. On the other hand when plowing hillsides, the plowman can always watch for the time when said power becomes slack as usually happens when turning at the end of a furrow, and then he can readily adjust the block 10, either toward the bolt 3 to lock the elevis for plowing the uphill furrow, or he can adjust the said block away from said bolt as just described for plowing the down-hill furrow. By thus adjusting the elevis 1 upwardly for up-hill furrows and downwardly for downhill furrows, said furrows are plowed to the same depth and the strain on the plowman is greatly lessened.

It is obvious that those skilled in the art may vary the details of construction as well as the arrangement of parts without departing from the spirit of the invention, and therefore, I do not wish to be limited to the above disclosure, except as may be required by the claims.

WVhat I claim is 1. In a plow the combination of a beam having a longitudinally disposed slot; a block adapted to reciprocate longitudinally of said beam in said slot; at elevis pivoted to said beam and having an extension adapted to be engaged and moved by said block; a lever; and connections between said lever and block formoving the latter, substantially as described.

2. In a plow the combination of a beam having a slot; a block adapted to reciprocate in said slot; a clevis provided with an extension pivoted to said beam and adapted to be moved by said block; a lever pivoted v to the plow; and connections between said plow; and connections comprising a pitman 10 lever and block for moving the latter, subbetween said lever and bloc for moving the V stantially as described; lattensubstantially as described. 7 3.
